Abstract

The present invention is based on the environment and condition that the image quality difference of the image is large according to the projection amount of light and the brightness of the light inside and outside the building. Therefore, it was designed to produce the maximum publicity effect by selectively exposing with two roll screens. If the image coming out of the beam projector is composed of the front-side roll screen and the transmissive double-sided roll screen as the integrated device, the user can simply lower the front-side roll screen in the building and raise the front-side roll screen if it wants to watch the image inside and outside the building. It is a multi-roll screen device that allows users to view images from both inside and outside the building by lowering the roll screen.

Description

Multi Roll Screen Unit {MULTIPLE ROLL SCREEN}

In this design, the transmissive double-sided screen alone does not meet the external environment and conditions in projecting light, so another front-only roll screen is mounted on the same frame, and it can be selectively used according to the environment and conditions. And it is designed to exhibit the image display effect.

Projecting a transmissive double-sided screen, which is a conventional technology, at midday, the amount of sunlight

There is a problem that one side of the image does not express the image and can not see the other shaving image properly, and the screen cannot be properly adjusted according to the installation environment and conditions, so that the image is not properly exposed.

The present invention was created in order to solve the conventional problems as described above, the object of the present invention is to select the screen selectively according to the amount of light and the installation environment, characterized in that to maximize the promotion and image display effect. .

Transparent window (1) of the building can be seen through the viewing of the video content using the transmissive double-sided screen as a boundary between the inside and the outside and the promotional material on the back of the front screen only. The screen materials of the transmissive double-sided roll screen device 2 and the front-side roll screen device 3 are in the form of sheets and films so that they can be easily raised and lowered. Since the beam projector 4 mounted inside depends on the image sharpness depending on the external environment and conditions according to the light, raise the transmissive double-sided roll screen at midday when there is a lot of external light, and watch the image in the building with the roll screen for the front. The publicity on the other side can be exposed to the outside. When the external light level is low, you can raise the front-side roll screen and use the transmissive double-sided roll screen to view the image projected on the double-sided roll screen from inside and outside. Thus, it is a manufacturing apparatus designed to produce the maximum display effect by maximizing exposure of image clarity by allowing the multiple installed screens to be easily selected and used according to the environment and conditions.

1 and 2 are explanatory views of the cross-sectional structure of the present invention.

-Designation of symbols for main parts of the drawings

The transmissive double-sided roll screen device 2 and the front-side roll screen device 3 operate separately from each other, and may be mounted at different intervals and positions depending on the conditions of the installation location. Each roll device can be easily rolled up or down, and can be easily moved up and down with a switch or remote control by installing a power transmission device.

As mentioned above, the present invention is a multi-roll screen device designed to maximize the publicity while providing the maximum clear image by selectively selecting the screen according to the external light condition and environment. Although the present invention has been described in connection with the above-mentioned preferred embodiment, it is possible to apply variously to a multi-screen and promotional product line in which an image is formed without departing from the spirit and scope of the invention. Therefore, the attached utility model registration claims are included in this family belonging to the gist of the present invention.
